Application of the intergranular impedance model in correlating microstructure and electrical properties of doped BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
Microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of this material. In this study, the model of intergranular impedance ...
Sensors for measurements of angular velocity and their application in agricultural machines / Senzori ugaone brzine i njihova primena u poljoprivrednoj tehnici
(Naučno društvo za pogonske mašine, traktore i održavanje, Novi Sad i Univerzitet u Novom Sadu - Poljoprivredni fakultet - Institut za poljoprivrednu tehniku, Novi Sad, 2008)
Measurements and control of angular velocity are encountered in many fields of industry, including in agricultural machines. Devices used for measurements of angular velocity are of mechanical or electrical type. The usage ...
Multivariate analysis in weed vegetation research: Examples from NW Balkans / Primena metoda multivarijantne analize u proučavanju korovske vegetacije na primeru severozapadnog Balkana
(Herbološko društvo Srbije, 2008)
Studies of weed vegetation by using Braun-Blanquet's method have been traditional in the north-western Balkans but only studies based on synoptic tables of weed vegetation have so far been conducted in the area of the ...
The effect of increased nitrogen amounts on the yield of green biomass and hay of forage sorghum, Sudan grass and their interspecies hybrid / Uticaj povećanih količina azota na prinos zelene biomase i sena krmnog sirka, sudanske trave i interspecijes hibrida
(Savez poljoprivrednih inženjera i tehničara, Beograd, 2010)
The area of the western Balkans is characterised with semi-arid climate, i.e. with hot summers and the unfavourable rainfall distribution. Growing maize silage has become unsafe, due to the appearance of long summer droughts. ...
Analysis of self-(in)compatibility in apricot cultivars using fluorescence microscopy
(Taylor & Francis Ltd, Abingdon, 2007)
Self-incompatibility is a common feature in fruit species of the genus Prunus, especially in sweet cherries and almonds. In apricot (Prunus armeniaca L.), although cultivars of the European ecogeographical group are generally ...
Effect of crop density on glasshouse tomato production / Uticaj gustine useva na proizvodnju paradajza u staklenicima
(Institut PKB Agroekonomik, Padinska skela, 2008)
Trials were conducted during winter and spring (January-June). The following four crop densities were investigated: 2,08; 2,50; 3,12 and 4,17 plants/m2. The properties monitored were: number of tomato fruits per plant, ...
